ROOT AND UNROOT SAMSUNG GALAXY PHONES
Before you begin: Rooting the phone will void its warranty. So you may have to install the stock firmware to get back your warranty. Make a backup of all the important data in your phone including contacts, messages and important applications. Make sure that your phone has more than 50% of battery. Install all the required Samsung USB drivers required to connect your mobile with PC. I would suggest you to install KIES 2.0 in your PC which will automatically install all the required drivers. Lastly don’t forget to enable USB debugging option in your phone.
